Dots are not used nearly as much in texting as they are in URLs as they are probably the most basic piece of URLs. And yes, that's the use of an address bar, whether or not you want to be purposefully ignorant or just plain ignorant of that. It's a rather basic concept when it comes to browser and the nature of address bars (even combined ones with search). That's pretty much what it comes down to, even if some might disagree that the should.
As you saw I also agreed about the period perhaps having a better placement, so no one was just blindly saying one extreme or another is it.
Sounds like you are set in your opinion of how it should be, which is certainly fine, but it doesn't change the basics of what certain elements are actually for what what comes with that.
If you feel you have to essentially jump on the poster to try to get your point across, well, that only speaks for the weakness of the point as a good one speaks for itself.
In any case I simply provided an explanation. Jumping all over it doesn't change it so there's not much more to be said about it really.
